Sangamon Astronomical Society is hosting the IDSSP at Jim Edgar Panther Creek conservation area September 13-16. Unfortunately it's the same weekend as Prairie Skies, so Illinois stargazers will have to choose.
As I understand it, Prairie Skies is turning into a nice event, more like the good old days of Astrofest, and that's a good thing. However, the last time I was at Camp Shaw, which was at least 10 years ago, the light pollution was pretty bad and unless the Kankakee/Bourbonnais area has shrunk, which I doubt, I can only imagine what it's like now. My only reason to choose Prairie Skies over IDSSP would be Gary's excellent "Prairie Dogs".
IDSSP however, has fairly good skies. There are small light domes from Springfield and Jacksonville, but on the whole, nice and dark. The local Lions club provides optional meals that can't be beat. The conservation area is really beautiful and at 20 miles away, Springfield is a nice little day trip with plenty to see. With no vendors, and minimal activities, this is a nice, low-key star party focused on observing.
You can still register for IDSSP through 9/1
